Description
Dogs' health and wellbeing is of great importance to their owners. The most common nutritional problem for pet dogs is obesity, with 22-40% of pet dogs being classified as overweight or obese. With many adverse health effects associated with obesity, this is a major concern for owners and veterinarians. The degree to which dogs enjoy consuming certain foods can have substantial implications for their body weight, so it is important to understand which aspects of foods make them appealing to dogs. This study aimed to determine whether nutritional aspects of commercial dog foods predict dogs' preferences for those foods. It was found that consumption preference is positively correlated with protein content (p < .001), therefore implying that the protein content of commercial dry dog foods may predict dogs' consumption preferences. Consumption preferences were not predicted by other available measures of food content or caloric value. Dogs' preference for foods high in protein content may be due to the satiating effect of protein. Since foods high in protein both reduce the amount of energy consumed and are found to be palatable to dogs, high-protein dog foods may offer a way for dog food manufacturers, veterinarians, and pet owners to combat obesity in pet dogs.

Description
Space microbiology, or the study of microorganisms in space, has significant applications for both human spaceflight and Earth-based medicine. This thesis traces the evolution of the field of space microbiology since its creation in 1935. Beginning with simple studies to determine if terrestrial life could survive spaceflight, the field of space microbiology has grown to encompass a substantial body of work that is now recognized as an essential component of NASA' research endeavors. Part one provides an overview of the early period of space microbiology, from high-altitude balloon and rocket studies to work conducted during the Apollo program. Part two summarizes the current state of the field, with a specific focus on the revolutionary contributions made by the Nickerson lab at the Biodesign Institute at ASU using the NASA-designed Rotating Wall Vessel (RWV) Bioreactor. Finally, part three highlights the research I've conducted in the Nickerson lab, as well as continuing studies within the field of space microbiology.

Breast cancer affects hundreds of thousands of women a year in the United States, and kills tens of thousands. African-American women experience a lower incidence of breast cancer, yet they die at twice the rate of Caucasian women. This disparity demonstrates the ineffectiveness of mammography at decreasing mortality in women at higher risk of late stage diagnosis. In this paper I argue that the continued support of the predominating idea that the benefits of mammograms strictly outweigh their negative effects may be a factor in the continued racial disparity in breast cancer mortality between African-American and Caucasian women. In addition, I will argue that mammograms are less effective for African American women because they are predisposed to later stage diagnosis and the accompanying poorer mortality prognosis due to higher-risk environments caused by varied socio-political status. My claims are supported by studies of incidence rates, survivorship versus mortality rates, screening usage rates, late stage and early stage diagnosis rate, tumor type, and the effects of socioeconomic status on stage of diagnosis. In particular, mortality rates have not decreased parallel with increased mammogram usage, especially in African-American women. Although early stage diagnosis has drastically increased, late stage-diagnosis remains unchanged and higher in African-American women. Tumor types vary by race, and African American women tend to have tumors that are highly prolific and more likely to be metastatic. Socioeconomic factors are more of a marker for breast cancer disparities than race, however race and socio-political structures that embody racism are often intersected.

Brief memory tasks for use with pet dogs were developed using radial arm maze performance as a standard comparison measurement of memory capacity. Healthy pet dogs were first tested in a radial arm maze, where more errors made in completing the maze indicated poorer memory. These dogs were later tested with five novel memory tests, three of which utilized a treat placed behind a box with an identical distracter nearby. The treat placement was shown to each dog, and a 35 second delay, a 15 second delay with occluder, or a 15 second delay with room exit was observed before the dog could approach and find the treat. It was found that errors on the delayed match to sample (35 second delay) and occluder/object permanence (15 second delay with occluder) tasks were significantly positively correlated with the average number of errors made in the 8th trial of the radial arm maze (r =.58, p<.01** and r =.49, p<.05*, respectively) indicating that these new brief tests can reliably be used to assess memory in pet dogs.

Since the 1960's, the sport of American football has maintained its stranglehold as the most popular sport in the United States. Both in viewership and participation, football has a massive lead on all other sports, but as of late many factors have led some to believe that trouble could be on the horizon. With various issues including head injuries, player protests, and television viewership decline plaguing football and its professional league, the NFL, the door could be open for another collision sport from across the pond to surge in popularity: rugby. Played in 119 countries by millions of people, rugby is currently one of the most popular sports in the world, but because of American football's dominance in the U.S. it has yet to really find its footing here; however, despite its popularity paling in comparison to football, rugby is actually the single fastest-growing sport in the U.S. Both sports share some strong similarities, and with football facing a myriad of issues, there is real reason to believe that rugby could be on the rise while football could continue to falter. By reading through articles and statistics on the subject, this thesis was divided into four main analysis topics to compare and contrast the two sports: injury problems and how they affect viewership and participation, international following for each respective sport, culture around the games themselves and how it could appeal to American viewers, and potential for growth domestically. By examining these factors within both sports, I was able to come to the conclusion that rugby's potential to take hold in the U.S. is growing, and in the coming years as American football's safety and importance continue to be called into question, rugby could one day even supplant football as the most popular collision sport in the country.

There are many anecdotal stories of dogs rescuing their owners from dangerous situations, but this rescue behavior has yet to be shown in an experimental setting. Studies have shown that dogs behave differently towards crying humans, but do not seek help for their owners when they are in distress. This study sought to determine if a dog could recognize when its owner was in distress and would attempt to rescue the owner. The experiment consisted of three conditions: a distress condition to determine how dogs respond to an owner calling for help, a reading condition to control for proximity-seeking and sound, and a food control to use as a basis for motivation and door-opening ability of the dog. Sixty dogs were tested in all three conditions in a pseudo-random order so that an equal number of dogs completed the conditions in each order. 38% of the dogs opened the apparatus for any condition, while 32% opened for the food and distress conditions and 27% opened for the reading condition, which shows that rescue in general is unlikely. There was no significant difference in the proportion of dogs who opened the apparatus for each condition, indicating that dogs are no more likely to rescue their distressed owners than they are to open the apparatus for other conditions and may not be able to sense that the owner is in distress. The similarities in the success rates also show that the owner can be just as motivating for a dog as food. Overall, the low success rates suggest that dogs are not generally likely to rescue a person who is trapped, even when they are calling for help.

Description
There are many parallels between human and equine sports medicine, including the roots of athletics, the development of specialized medicine, and injuries to the athletes. The most remarkable similarities are seen in tendinopathies. Because of the similarities between human and equine tendons, equine athletes serve as one of the best animal models to study tendon physiology and tendon injuries for application to human medicine. Because of this, many therapies have already successfully crossed from one realm of sports medicine to the other, the most notable of which are stem cell therapy, Interleukin-1 Receptor Antagonist (IRAP), and platelet rich plasma (PRP) therapies. There are also several therapies on the horizon that are very promising to potentially be successful in both human and equine athletes. However, some of these novel therapies are raising ethical questions. There are many regulations in place to protect against or address potential ethical conflicts in human medicine. The same trend is not seen in equine medicine. While there are rules enforced by many equestrian federations regarding ethical concerns and veterinary medicine, the information is not nearly as complete as it should be. Because they lack the autonomy that typical human patient possesses, equine athletes require significantly more advocacy from their veterinarians than human athletes do from their physicians. Additionally, there is a lack of large animal model studies secondary to cost and overall value of equine athletes to their owners, riders, and trainers. Ultimately it becomes an issue of veterinary ethics whether to pursue a novel or conventional treatment for an equine athlete. With biotechnology advancing as quickly as it is, new studies must be done and new regulations must be written in order to keep all fields of sports medicine operating safely and ethically for all athletes involved, regardless of species.

Description
Ten percent of the global population believed that the world would end on December 21, 2012. But people have believed that the world was going to end before. What causes these apocalyptic crazes and what allows them to spread beyond the fringes of society? What role does popular religion play in creating or spreading apocalyptic hysteria? How do these prophets of doom react when the world still exists past its predicted date of expiration? What about the people who believed them? This paper examines historical instances of apocalyptic predictions, how these predictions were formed out of or shaped by popular religion, as well as the reactions \u2014 both internal and external \u2014 of those who either predicted or believed that the end was near. After building this historical context, I turn my focus to the pop culture phenomenon that is the end of the Mayan Calendar. I attempt to understand and explain what aspects of the current social, religious, and psychological climate have contributed to the cultural ubiquity of and fascination with the December 21, 2012 apocalypse, and what the date actually meant to the Classical Maya. Finally, I examine the existential, religious, and cultural factors that make Americans in particular so ready and willing to believe that the end of the earth is imminent.

Description
Vaccine opposition is a growing problem in developed countries where dropping vaccination rates threaten general public health by laying the foundation for resurgence and reemergence of previously eradicated infectious diseases. This thesis argues that the current movement is only the most recent incarnation of opposition that has co-evolved with vaccine practices for the duration of their mutual histories. Part one provides a historical context for the current movement using the example of the development and deployment of the smallpox vaccine as a representative timeline of vaccine acceptance and opposition. Part two describes the current movement in the United States and the United Kingdom, interprets the reasons for the conclusions drawn by vaccine-concerned parents, and provides a framework for public health officials to approach the issues.

Description
Previous research pertaining to dog memory and cognition has been confined mainly to samples of colony dogs and therefore can be hard to generalize to a larger population of pet dogs and varying breeds. The present study focused entirely on pet dogs of many different breeds, rather than colony or laboratory animals for the purposes of accessibility, affordability, and novelty. Methods: We presented the dogs with a memory task in the form of a game in which the dogs chose to search for food at one of two locations at varying delay intervals, with a maximum time limit of one hour per dog. We expected our data to show a significant decrease in memory capacity and an increase in error rates among older dogs as compared to younger dogs; these results would allow us to conclude that it is likely many dogs, much like humans, experience various cognitive deficits as a function of increasing age. Results: Using one-factor ANOVA and linear and curvilinear regression analyses, we examined the relationship between the independent variable, age (individual dog ages as well as three generalized age categories), and three dependent variables. The dependent variables were: (a) percentage of correct choices at a 60 second delay interval, (b) maximum delay interval attempted (MDIA), and (c) the maximum delay interval that was completed above chance level (50%) (MDAC). We found significant results to support our hypotheses that aged dogs show spatial memory and cognitive deficits in comparison with young and middle-aged dogs, and that age can be considered a marginally significant predictor of spatial memory capacity.
